How to convert M4A to Ogg

Open an M4A, such as a voice memo or a song, and save it as Ogg for a game, a web page, or an app that wants an open format. The M4A to Ogg converter runs in your browser, so the file stays on your device.

  1. Step 1

    Choose your M4A files
    Pick one or many, or drop them into the converter above.

  2. Step 2

    Keep Ogg
    Ogg is selected; choose another audio format if you need one.

  3. Step 3

    Download the Ogg
    Save each file when it's converted.

What to expect

Supported inputs
M4A files and any other audio or video file.
What happens
The AAC sound is re-encoded as Opus in an Ogg file. Ogg is selected first; you can choose another audio format.
Limits
Copy-protected M4P songs can't be converted. Very long recordings depend on your device's memory.

Questions

Game engines, some Linux apps, and sites that take only open formats ask for Ogg.

Opus, which sounds as good as AAC at the same size.
